Video

Thanks alot . You're helping me a lot with the learning electronics .

thanks...!”

Thanks for this video! Been enjoying going through this series. At 1:49 I don't think you have to assume Vf = 1. You can see in the equation that Vf is on both sides of the equation, so you can simply divide both sides by Vf to remove it. This tells us that the rise time of 2.2RC doesn't depend on the value of Vf :)

I went over and over, and over how the f to get the R needed for the equation 1/(2piR*Fc). I re read my basic capacitor laws, resistance laws and the entire book that took me 3 years to finish.. Thank you so much for making it clear, I did not know Re * Beta had to be included for R. I was just using the parallel answer and using high filter. So glad for these videos. Now I can move on with confidence Thank you 😅

Just saying - The problem requires power supplies of + and - 15V not 15V to ground.

A build would be nice to see what it does.

Excellent, thank you!

please help.. i can’t figure out where the percentage taken from? 94% and 60%.

Thanks for the video! At 6:23, I think the second last line should say: = 15 * 10k/(5k+10k) You may have accidentally used the voltage source from the previous part.

I tried to use this circuit to linearly charge a capacitor but it was hard to figure out the math for it. I instead just used a basic voltage regulator in parallel with the capacitor to linearly charge the capacitor. Though I still only know the basic math for it.

In exercise 1.6 isn't the correct value for 0.05 micro ohms 0.05x10^-6 rather than 0.05x10^6. Then the cable length and temperatures would be much more realistic?

This is very interesting. I went about it a different way, I see the 5% drop spec to come up with a load resistance of 10 ohms. From there, I got the source resistance of 510 ohm using equation 2.2. And then used the thevenin equivalence to come with voltage divider values which come out to be pretty close to yours. I think the way you calculated Ib is strictly speaking incorrect as 25mA is the emitter current and not the collector current.

Thank you very much for the solution video! Hope it keeps going, because I can't really find any written solutions for The Art of Electronics, which is annoying!

Awesome to find this resource; great help! I'm looking forward to the later chapters and will be following along!

Thanks...!”

Thank you for the video. I've just bought The art of electronics book, third edition but I'm struggling to find which page it's on. Is there a chance of letting us know which page it is. Thanks again.

Nice series!

Nice video. You did a great job focusing on key points without getting sidetracked. It would be all too easy to make this much longer. Thanks!

comprei o livro e estou aprendendo aqui no Brasil! Parabéns pelo projeto!

Hey great video really like the explanation. I have gotten answer where close to your answer for example for resistance in the first one i got 0.25 ohms and for second 20000 ohms. However i did not use kcl or kvl to solve them. After I calculated the voltage using ohms law V=IR for the given value (50uA)(5k) and when it came to finding the shunt resistance i would use ohms law again and assume the largest value in the both domain they have given us for the first one i just assumed the current to be 1A and solved it like that using Ohms law and got 0.25 ohms and for the second one i did same thing let voltage =10v and divided it by 50uA and got the answer 20000 ohms. I just want to know is my method right. Thank you for your time.

Great vid man glad it working first time!

Hey man, I'm so glad I came across this series. I've always wanted read this book in it's entirety and this has been my sign. Please keep it up, I'll be following along for the journey!!

Hi bro, nice video and I love your work rate. You’ve help me out a lot with electronics. I was wondering if you could make a video on how to use pcb way or jlcpcb to order the boards and parts. I’ve been trying to do this for a week and it’s not making sense.

awesome thankks!!

Oh wow! Beating Guinea. What an achievement. I'm sure that the FIFA Top 10 squads are shaking in fear!

Great! Subscribed and will join.😊 I didn't notice the book photo at beginning of your videogram as it was only shown briefly, eventually discovered that you are referring to "The Art of Electronics 3rd Edition" manual (not the "Learning the Art of Electronics hands-on manual). And your first diagram refers to page 78. Noting other peoples' comments, I should say that my TAOE books have been sitting unused for some time, and it is great that your videograms encourage me to dust them off and use them again. Thank you ! 😊❤😊

awesome vid dude!

Thanks 🙏👍💯😊

Can you review PicoScope?

i want to ask from the exercise 1.6, where did we get 7.72x10^4 and what is the unit measure of it? it is question c.

where we got the area of 7.72x10^4?

very helpful!

To get a transistor in full saturation a safe rule of thumb is to have a Ib 10 times higher than is needed. That would make the beta required 240. Remember that when a transistor is in saturation the collector voltage is 0.1V. With a base voltage of 0.7V part of the base current does not only flow to the emitter but also to the collector. Therefore a safety factor of 10.

Nice video. What about filling top and bottom layer with GND as well? Can't you look at gerbers in KiCad? I always do check them in Altium. JLCPCB has online gerber viewer as well and recently I noticed there is even DFM check. I checked it out yesterday and it was decent. When it comes to USB protection I took out USBLC6-2SC6 part and used ECMF02-4CMX8. The reason why USBLC6-2SC6 sucks is it's VBUS connection. There is a connection between VBUS and D+/D- lines. If you disconnect your USB so VBUS should drop to 0, but your D+ or D- is pulled to high then your VBUS will be like at 2.5V. I also noticed recent ST schematics using USBLC6-2SC6 with external additional TVS diode so they won't connect VBUS connection and use another standalone TVS there. I personally don't like USBLC6-2SC6 for this reason. If I use it I will not connect VBUS and do the same - use another TVS on VBUS.

Best electronic video ever. Thank you. 🙏

awesome work man! channels gonna blow up soon!!

Hi great video. Thank you. Can you put a link to the schematic and bill of materials

Let me know if you have any questions or suggestions. thanks for watching!

TAE is amazing books serie( book 2 is a top) but make a vid about is the "amazing" ....thank u sir....as always say "if u want to know something in electronic build it"

Or use Darlington transistor with VAR POT to adjust Ic of Q3.

This is such a great tutorial. One question, how would one know to convert time constant to natural log?

You should consider to use another mouse pointer, it's not very easy to spot where it is on a white background, and keep up with the explanation! Thanks for the video

Thank you for the video. One of my favorite classes in college was this lab with Tom Hayes...over 30 years ago now. Your video brings back some good memories. Very clear explanations. If I might make a comment, I would have liked you to return to the example of setting R5 to 100k to see that while you do improve the output voltage level then you need a much higher beta for Q5--emphasizing the tradeoffs (if I have that right). I'm jumping in in the middle as I just saw the article on hackaday, so don' know if you covered it before but yes more transistor theory would be great as well as more discussion about how the output pulse length is determined by component values--maybe you did that in another video. I look forward to watching more.

In order to achieve a full zero to +5V swing at the output, I could try using a logic level, enchancement mode (N-channel) MOSFET. By doing so, loading effects would be negligible during steady state conditions

Good stuff. I have made a ton of transistor related circuits playing with wave form outputs. I learned a lot playing with resistance and capacitance making many wave forms. For instance I would take a single pulse and make it a sawtooth, or a sine wave or a longer or shorter pulse all with a couple of teansistors. Its amazing how we can take one signal and modify it to get our desired output. This circuit you have reminds me of the lightening detector I built. I wanted the sharp small pulse of the lightening to last a bit longer for a better visual effect on the LED strip, so I spent an hour or so getting it tuned to look nice visually with a very similar circuit stretching out the duration of the pulse. It came out nice. Its an LED lightening bolt on the wall, and when lightening is anywhere within 5 to 10 miles from the house it starts blinking in time with the actual lightening outside. At first it was too fast, i wanted it to fade out, and last a bit longer so thats where this part of the circut came in. Its a neat project you can add to this circuit to get a nice visual indication of local weather.

Yes great project!

Thank you for taking the time, love to learn something new.

+5Vcc and input of Q1 are connected to each other? i don’t know what is step input is?

Thanks for the video. If you understand how these transistor circuits work... why use the "Art of Electronics' for a videod. IMO... though it was quite a 'popular' book... it's quite outdated. Again... IMO... the "Art of Electronics" ... whatever edition... only survives.. because of it's cult like status... among those who thing it can 'explain' or 'teach' them electronics... a sort of 'short cut'... if you like... that wasn't a justified belief, when the book came out... and isn't justified now.

LT spice works better than spreadsheet. If you want pulse, you should look after NE555 this schematic pattern is more obvious for anybody.
